Sarr was able to get in front of Walker at the back post to pounce, also getting the better of his club teammate Dean Henderson in the process.
Upon analysing the equaliser, Keane - on punditry duty for ITV - singled out Walker for criticism, going as far as to accuse the experienced defender of being “lazy” in the build-up to the goal.
He said: “If this is a young right back, you're thinking it's inexperience.
“But I think he's being lazy.
“He almost can't be bothered getting back. For a vastly experienced player, you can't be making mistakes like that.”
England head coach [Thomas Tuchel](/topic/thomas-tuchel) is unlikely to be pleased with Walker’s defending either after being very critical of the team’s overall performance against Andorra at the weekend.
Despite a 1-0 win in the World Cup qualifier, Tuchel felt the display was lacklustre and called for an immediate response in the international friendly against Senegal on Tuesday night.
